As in [1]}, we consider pressure-driven flow of an incompressible viscoelastic fluid in a channel bounded by two parallel, stationary, rigid plates separated by a distance of \(2h\) .
We model viscoelasticity using the FENE-P model so that the governing equations are
 

Re [ t u+ ( u\( \nabla \)) u]+ \( \nabla \)p = u+ (1-) \( \nabla \) +
